Spring Constructor Injection Example

Date: 2017-09-13

This tutorial demonstrates Spring's constructor-based dependency injection. It explains dependency injection as a design pattern that reduces object dependencies and improves testability by outsourcing object instantiation to a third party (like the Spring container). The tutorial walks through creating a Maven project in Eclipse, setting up the necessary dependencies (Spring Core, Spring Context), and building Java classes (Department and AppMain) along with a Spring configuration file (spring-beans.xml). This configuration file defines beans and their dependencies, allowing Spring to inject them during object creation. The example showcases how to inject dependencies into a class via its constructor.
